TELEGRAPH SENDING-MACHINE.

To all whom it may concern Be it known that I, Josnrn M. KENNEDY, acitizen of the United States, and resident I of St. Louis, Missouri, have invented certain new and useful Improvements in Telegraph Sending-Machines, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in telegraph sending machines, and the primary object of my invention is to construct a sending machine of the type having a vibrator for forming dots with a key which is moved vertically, so that in the formation of dots the normal or natural vertical move natural vertical movement for the operation of the vibrator and to combine with this key a second key movable independently of the first mentioned key for the formation of dashes, the second mentioned key having the ordinary natural vertical movement.

lVith the above purposes in view my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claim and illustrated by the accompanying drawings, in which Figure 1 shows in plan a telegraph sending machine constructed according to my invention; Fig. 2 shows in elevation my improved sending machine; Fig. 3 is a transverse sectional elevation of the machine taken on the line 33 of Fig. 1; Fig. 4: is an enlarged elevation partly in section showing the relative arrangement of the two keys; and Fig. 5 is an inverted plan of the instrument.

Referring by numerals to the accompanying drawings: 6 designates the base constructed of material possessing electrical conductivity. Carried by the base and on its underneath face are the cushioned feet 7. On the upper face of the base adjacent the forward end thereof is a yoke 8 which yoke is in electric circuit with the base.

D pe ding from the y ke adja ent ne of Specification of Letters Patent.

the standards thereof is an ear 9 arranged to form with said upright arm of the yoke a support for a pivot pin 10. 'Mounted for vertical rocking movements on the pivoted pin 10 is a lever 11. At the outer or forward end of the leverll there is a key 12 having a central vertical bore 13 therethrough. Carried by the yoke to one side of the ear JOSEPH M. KENNEDY, OF, ST. LOUIS, MISSOURI, ASSIGNOR 0F ONE-HALF TO EDVVAZRZD PatentedAprA, 1916. Application filed December 5,1913. Serial No. 804,897. 1

9 is a pivot bolt 14, and pivotally connected with said bolt in a manner to move in a horizontal direction is a bar 15. Carried by the bar at its forward end and in the path of travel of the lever llis an inclined plane 16 whereby when the key 12 is'depressed'the lever 11 will be vertically rocked and engage the inclined plane 16 'to effect a lateral or horizontal rocking of the bar 15. Carried by the bar 15 through the medium of a metallic leaf 17 is a vibrating arm 18 carrying a movable weight 19. Secured to the base and arranged to engage the vibrating arm 18 is a stop 20 and carried by the yoke 8 is a pair of adjusting screws 21 arranged to control the movement of the bar 15. Carried by the vibrating arm 18 is a yielding contact point 22. Arranged in the path of but which is connected with the binding post 25 through the medium of an insulated conductor 28 and the insulated conductor 26,

. and a verticallymovable contact 29 carried upon a vertically movable pin 30 in electric circuit with the base and carrying an insulated key 31 nested within the bore 13 of the key 12. The contact point is preferably secured to a collar 32 which is secured to the pin 30. Embracing the pin 30 and impinging between the collar 32 and the base 6 is an extensile coil spring 33 whose office is to 4 hold the key 31 and. contact 29 in elevated positions.

cut in and out of circuit the plate 27.

In the practical operation of my machine,

assuming it to be in electric circuit with a sounder and the switch'35 open, the operator places his fingers upon the key 12 and, by the regular and normal vertical movement as is used in connection with all Morse machines, depresses the key 12 when it is desired to produce dots. By the adjustment of the weight 19 and the set screws 21 the desired movement of the vibrating arm is established and the number of dots is controlled entirely by the duration of the touch of the key 12. Without any appreciable shifting of the hand or any of the fingers the operator can practically through a onekey arrangement depress the key 31 and establish a connection through the contact Copies of this patent may be obtained for five cents each, by addressing the Commissioner of iatents,

point 29 and plate 27 to produce dash or i dashes.

It is obvious that both the dot and the dash are accomplished through the medium of the ordinary and natural vertical move-' ments of the fingers and that the machine may be quickly learned, and speed and ac without the acquiring of a two vertically and independently movable keys, one of which keys is provided with a bore through which the other key is operable, and means associated with each key for making and breaking an electric circuit, one;

of which means includes a vibratingelement.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses. is
